A vertical line is perpendicular to the x-axis because they would intersect to form a 90 degree angle.
Simplify each term.
1/2X - 1/3Y
Combine 1/2x and −1/3y using a common denominator.
To write −1/3y as a fraction with a common denominator, multiply by 2x/2x.
(1 / 2x )(3y / 3y) + (−1 / 3y) (2x / 2x)
Write each expression with a common denominator of 6xy, by
multiplying each by an appropriate factor of 1.
1 (3y)/6xy − 1 (2x)/6xy
Combine the numerators over the common denominator.
1(3y) − (1(2x))/6xy
Simplify the numerator.
3y−(1(2x))/6xy

It's 6/12 then 1/2. Good luck
Answer:
D) 36 bottles for $4 by 1.4¢ per bottle
Step-by-step explanation:

#A
Bottles/Dollar=
bottles/dollar
#Both B and C charges the same as A and will have bottle/dollar ration of 8:1
#D
Hence, D is the better buy as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.
